Question

I am new to python and OpenCV coding. I am reading a video from my webcam. I want my code to be able to capture an image when i click anywhere on the window which opens the video. This is the piece of code which reads the video. Please suggest how I can do this.

cam = create_capture(video_src, fallback='synth:bg=../cpp/lena.jpg:noise=0.05')

while True:
ret, img = cam.read()
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
gray = cv2.equalizeHist(gray)
t = clock()
rects = detect(gray, cascade)
vis = img.copy()
draw_rects(vis, rects, (0, 255, 0))
for x1, y1, x2, y2 in rects:
roi = gray[y1:y2, x1:x2]
vis_roi = vis[y1:y2, x1:x2]
subrects = detect(roi.copy(), nested)
draw_rects(vis_roi, subrects, (255, 0, 0))
dt = clock() - t

draw_str(vis, (20, 20), 'time: %.1f ms' % (dt*1000))

cv2.imshow('facedetect', vis)
if 0xFF & cv2.waitKey(5) == 27:
break
## CODE SHOULD CAPTURE AN IMAGE ONCLICK

cv2.destroyAllWindows()
